PHOTOGRAPHIC-PRINTING APPARATUS.

Specification forming part of Letters Patent No. 75,482, dated March l0,186B.

A erence being had tothe accompanying drawings, making apart .of thisspecification, in which- Y Figure l is a perspective view of my haloprinting apparatus; Fig. 2, the oval, roundly, or otherwise beveled diskor halo-formater; Fig. 3, a profile View of the same, with its centralcolumn or handle and cord-supporter;

Fig. '4, a covering-screen, of ground glassware,'tissuepape r, or othertransparent medium, to produce a diffused reflection of transmittedlight, round or oval in form, o r-other- Wise, to produce the result.

The nature 0r object of my invention consi sts in producing a new styleof photographs, which I call the cabinet-portrait style, preseliting abeautifully-graduated halo around the figure, reversing the vignettestyle, by having the outer edges dark, from any shade a jet black,instead of the glaring White margin, so easily soiled, and 'inclined toturn into a dirty yellowish color in time.

To enable others skilled inthe business-or art to make and use myinvention, it is only necessary to say that I procure a smooth board,-of the desired size, raised from the table by -short feet or stripsbeneath, to facilitate the handling.

F represents this printing-board, and f thel ledges across the bottom.Gare four spring or turning clamps, to hold the picture P.

The halo-formatorA has a central fiat disk, B.} .This covers the lfaceand high lights of the picture, previously printed. by the ordi---naryprinting process in, vogue for l vignette The outer portion of theformto a thin edge aroundthe circumference bethe form oval, circular, orotherwise. '.l7 or perforated handle cis axed tothe beveledphotographs.A

formator A, of any desired length'.

Gum-'elastic cords D D are passed through the perforations in the topofv the, column', crossing each other at right angles, each end of the'cords terminated by a loop or its equivalent, to attacn over4 a headed'.nail,-

he ,central column knob E, o its equivalent, which stays the combinedhalo-formater AB C in its posi! tion, and admits of .its being easilyhandled, as well as turned upto change the pictures, with the greatestfacility. p

In' order that the same handle@ may be applied to variously-shapedformators A, I use a bolt with a head. countersunk i'nto the center ofthe disk or formater A, with a nut on the screw end of the bolt tofasten the same.- I also find it convenient to use gum cords, stretchedacross the printing-board F, parallel-to each other, from one corner tothe other,under which the plate and paper are readily slipped and heldin place. By the use of beveled oblong slots, these cords can beadjusted nearer to or more -remotelyfrom'each other, in place of theclamps G, shown in the drawing.

The operation will be understood by the foregoing` description oftheapparatus einployed-that is, as fast as the photographs are printedin the ordinary manner. they 4are placed at P, on the printing-board F,the halo-formator A B C D adjusted, and the light will strike around andmore diused or scattered under the beveled disk A. By4 judicioushandlingand exposure to the action' of the light,'the effect can belvaried froma light halo, deepened more or less at pleasure, to

suit the taste of the operator, andthe ,mostl beautiful and softenedgradationscan be pro duced eby this appliance, not to be reached by anyother process heretofore in use, and introduces a new style ofcabinet-pictures to the public, highly appreciated by persons of taste.

I am aware that pictures presenting a kind of halo are producedbyplacing a darkened diaphragm in front of the lens, either in or before`the camera.` This gives, usually, unsatisfactory results, and differssubstantially from my additional printing process, which I believe'new,and never before used.v I there; fore do not broadly claim the halosurrounding photographs, but the 'combined secondary printingfframe,with or without a screen, H. 'What I claim as my invention, and desireto secure byLetters Patent, is-

The additional printing process, substantially` inthe manner specified.
